(the "Company"). All terms not otherwise defined herein shall have the meanings ascribed in the Schedule 13D. This Schedule 13D is reporting matters with respect to the group consisting of Jack E. Golsen, Sylvia H. Golsen, SBL Corporation ("SBL"), Golsen Petroleum Corporation ("GPC"), a wholly owned subsidiary of SBL, Barry H. Golsen, Steven J. Golsen and Linda Golsen Rappaport. This Amendment No. 25 to the Schedule 13D is being filed as a result of a change in the facts contained in Amendment 24 to the Schedule 13D.

Mr. Golsen did not acquire any shares of Common Stock under the nonqualified stock option prior to its expiration, and the expiration resulted in a decrease in Mr. Golsen's beneficial ownership of Common Stock by more than 1% of the outstanding Common Stock. Item 1. Security and Issuer. Item 1 of this Schedule 13D is unchanged. Item 2. Identity and Background. Item 2 of this Schedule 13D is unchanged. Item 3. Source and Amount of Funds or Other Consideration. This item is not applicable to the expiration of the Expired Option described above. Item 4. Purpose of Transaction. Item 4 of this Schedule 13D is unchanged. Item 5. Interest in Securities of the Issuer. (a) The following table sets forth as of June 1, 1999, the aggregate number and percentage of the class of Common Stock of the Company identified pursuant to Item 1 beneficially owned by each person named in Item 2: Page 10 of 23 Pages

Lender also may (but shall not be obligated to) pay all costs for insuring, maintaining and preserving the Collateral. All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Grantor. All such expenses shall become a part of the Indebtedness and, at Lender's option, will (a) be payable on demand, (b) be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either (i) the term of any applicable insurance policy or (ii) the remaining term of the Note, or (c) be treated as a balloon payment which will be due and payable at the Note's maturity.

Except as provided above, Lender shall have no liability for depreciation or deterioration of the Collateral. EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default under this Agreement: Default on Indebtedness. Failure of Borrower to make any payment when due on the Indebtedness. Other Defaults.

Sell the Collateral. Sell the Collateral, at Lender's discretion, as a unit or in parcels, at one or more public or private sales. Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized public market, Lender shall give or mail to Grantor, or any of them, notice at least ten (10) days in advance of the time and place of any public sale, or of the date after which any private sale may be made. Grantor agrees that any requirement of reasonable notice is satisfied if Lender mails notice by ordinary mail addressed to Grantor, or any of them, at the last address Grantor has given Lender in writing.

Sell any securities included in the Collateral in a manner consistent with applicable federal and state securities laws, notwithstanding any other provision of this or any other agreement.

Borrower agrees, to the extent permitted by law, to pay any deficiency after application of the proceeds of the Collateral to the Indebtedness. Cumulative Remedies. All of Lender's rights and remedies, whether evidenced by this Agreement or by any other writing, shall be cumulative and may be exercised singularly or concurrently. Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election top make expenditures or to take action to perform an obligation of Grantor under this Agreement, after Grantor's failure to perform, shall not affect Lender's right to declare a default and to exercise its remedies. MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of this Agreement. Amendments. This Agreement, together with any Related Documents, constitutes the entire understanding and agreement of the parties as to the matters set forth in this Agreement. No alteration of or amendment to this Agreement shall be effective unless given in writing and signed by the party or parties sought to be charged or bound by the alteration or amendment.

Borrower and Grantor agree to pay upon demand all of Lender's costs and expenses, including legal expenses, incurred in connection with the enforcement of this Agreement. Lender may pay someone else to help enforce this Agreement, and Borrower and Grantor shall pay the costs and expenses of such enforcement. Costs and expenses include Lender's legal expenses whether or not there is a lawsuit, including legal expenses for bankruptcy proceedings (and including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection services. Borrower and Grantor also shall pay all court costs and such additional fees as may be directed by the court. Caption Headings. Caption headings in this Agreement are for convenience purposes only and are not to be used to interpret or define the provisions of this Agreement. Multiple Parties. All obligations of Borrower and Grantor under this Agreement shall be joint and several, and all references to Borrower shall mean each and every Borrower, and all references to Grantor shall mean each and every Grantor. This means that each of the persons signing below is responsible for all obligations in this Agreement. Notices. All notices required to be given under this Agreement shall be given in writing, may be sent by telefacsimile (unless otherwise required by law), and shall be effective when actually delivered or when deposited with a nationally recognized overnight courier or deposited in the United States mail, first class, postage prepaid, addressed to the party to whom the notice is to be given at the address shown above. Any party may changes its address for notices under this Agreement by giving formal written notice to the other parties, specifying that the purpose of the notice is to change the party's address. To the extent permitted by applicable law, if there is more than one Borrower or Grantor, notice to any Borrower or Grantor will constitute notice to all Borrower and Grantors. For notice purposes, Borrower and Grantor will keep Lender informed at all times of Borrower and Grantor's current address(es). Severability. If a court of competent jurisdiction finds any provision of this Agreement to be invalid or unenforceable as to any person or circumstance, such finding shall not render the provision invalid or unenforceable as to any other persons or circumstances. If feasible, any such offending provision shall be deemed to be modified to be within the limits of enforceability or validity; however, if the offending provision cannot be so modified, it shall be stricken and all other provisions of this Agreement in all other respects shall remain valid and enforceable. Successor Interests. Subject to the limitations set forth above on transfer of the Collateral, this Agreement shall be binding upon and inure to the benefit of the parties, their successors and assigns. Waiver. Lender shall not be deemed to have waived any rights under this Agreement unless such waiver is given in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A waiver by Lender of a provision of this Agreement shall not prejudice or constitute a waiver of Lender's right otherwise to demand strict compliance with that provision or any other provision of this Agreement. No prior waiver by Lender, nor any course of dealing between Lender and Grantor, shall constitute a waiver of any of Lender's rights or of any of Grantor's obligations as to any future transactions. Whenever the consent of Lender is required under this Agreement, the granting of such consent by Lender in any instance shall not constitute continuing consent to subsequent instances where such consent is required and in all cases such consent may be granted or withheld in the sole discretion of Lender.

Declare all liabilities secured hereby immediately due and payable, and/or proceed to enforce payment and performance of all liabilities secured hereby. 2.

Lender shall have acted in a commercially reasonable manner if its action or non-action is consistent with the general usage of lenders in the area of Lender's location at the same time the action or non- action occurs, but this standard shall not constitute disapproval of any procedures which may be otherwise reasonable not require Lender to take necessary steps to preserve rights against prior parties in an instrument or chattel paper.

Undersigned agrees promptly to reimburse Lender for all such expenditures and until such reimbursement the amounts of such expenditures shall be considered a liability of Undersigned to Lender which is secured by this Agreement. In addition, Undersigned shall be liable for and agrees to pay Lender for all costs, attorneys' fees and other disbursements by Lender as allowed by law or provided for herein in the enforcement or collection of any note, warranty or duty of Undersigned to Lender, or in the realization upon or the enforcement or collection of any account, receivable, contract right, promissory note, chattel paper, instrument, document or other Collateral in which Lender has a security interest.

Applicable Law. The law of the jurisdiction where Lender is organized or holds its certificate of authority the Undersigned who was entitled thereto shall control this Agreement. 4. Waivers. No act, delay or omission, including Lender's waiver of remedy because of any default hereunder, shall constitute a waiver of any of Lender's rights and remedies under this Agreement or any other agreement between the parties. All rights and remedies of Lender are cumulative and may be exercised singularly or concurrently, and the exercise of any one or more remedy will not be a waiver of any other. No waiver, change, modification or discharge of any of Lender's rights or of Undersigned's duties as so specified or allowed will be effective unless in writing and signed by a duly authorized officer of Lender, and any such waiver will not be a bar to the exercise of any right or remedy or any subsequent default. Undersigned hereby waives: (a) all demands and notices of any action taken by Lender under the Agreement or any other agreement between the parties or in connection with any notes; (b) an indulgence of Lender; and (c) any substitution for, exchange of, or release of all or any part of the Collateral or of other Collateral securing obligations of Debtor to Lender. Undersigned also consents to the addition or release of any person liable on any obligation of Debtor or Undersigned to Lender. 5. Agreement Binding on Assigns.

Rights of Lender Assignable. Lender at any time and at its option may pledge, transfer or assign its rights under this Agreement in whole or in part, and any pledgee, transferee, or assignee shall have all the rights of Lender to the rights or parts thereof so pledged, transferred or assigned.

Separability of Provisions. If any provision of this Agreement shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, and this Agreement shall be construed as if such invalid or unenforceable provision had never been contained herein. 9. Copies. A carbon, photographic, or other reproduction of this Security Agreement or of any financing statement prepaid or filed with respect hereto is sufficient as a financing statement. 10. Notice of Name Change, etc. Undersigned will immediately notify Lender of any change in his, her, its or their name, identity, or organizational or corporate structure.

A.   To induce the Lender to extend credit to the Debtor and for
     other good and valuable consideration, the receipt of which is
     acknowledged, and for the purpose of enabling the Debtor to
     obtain or renew loans, credit or other financial accommodation
     from the Lender named above, each of the undersigned as a
     primary obligor, jointly and severally and unconditionally:
     (1) guarantees to the Lender that Debtor will fully and
     promptly pay or otherwise discharge all indebtedness and other
     obligations ("indebtedness") upon which Debtor now is or may
     later, from time to time, become obligated to Lender as
     principal, guarantor, endorser, or in any other capacity, and
     whether joint or several liability or liability created by
     direct dealing with Lender or through transfer from others,
     and regardless of the nature and form of indebtedness and
     whether due or not due; (2) agrees, without the Lender first
     having to proceed against Debtor or any other party liable or
     to liquidate any security, to pay on demand all sums due and
     to become due to Lender from Debtor, and all losses, costs,
     reasonable attorney fees or expenses which may be suffered or
     incurred by Lender by reason of Debtor's default or the
     default of the undersigned; (3) except as setoff is waived,
     agrees to be bound by and on demand to pay any deficiency or
     difference between all indebtedness of the Debtor and the
     proceeds of any private or public sale (including a sheriff's
     sale) of the security held by Lender, with or without notice
     to the undersigned; (4) agrees that liability under this
     Agreement will not be affected or impaired by any failure,
     neglect or omission, including a failure or delay to perfect
     or maintain perfection of a security interest, either in
     relation to the collection of the indebtedness or the
     protection of the security given, and regardless of whether
     the Lender fails or omits to seek or is precluded from seeking
     a judgment against Debtor; and (5) further agrees that the
     liability of the undersigned shall not be affected by any lack
     of validity or enforceability due to defense, claim, discharge
     or otherwise of any indebtedness guaranteed by this Agreement
     or of the security of the indebtedness.

B.   Lender may at any time and from time to time without the
     further consent of or notice to the undersigned, without
     incurring responsibility to the undersigned and without
     impairing or releasing the obligations of the undersigned, and
     upon any terms and conditions the Lender may elect: (1) change
     the manner, place or terms of payment or extend the time of
     payment of any indebtedness of Debtor to Lender; (2) renew,
     increase or alter any indebtedness of Debtor to Lender; (3)
     raise or lower the interest rate or rates charged Debtor; (4)
     sell, exchange, release, surrender, realize upon or otherwise
     deal or not deal with in any manner and in any order any
     property at any time pledged to secure or securing the
     indebtedness of Debtor to Lender or any liabilities incurred
     directly or indirectly under this Agreement, or any offsets
     against any such indebtedness or liabilities; (5) exercise or
     refrain from exercising any rights against Debtor to others,
     or otherwise act or refrain from acting; (6) settle or
     compromise any indebtedness guaranteed or incurred; (7)
     subordinate the payment of all or part of any indebtedness of
     Debtor to Lender to the payment of any liabilities which may
     be due Lender or others; (8) apply any sums paid by or for
     account of debtor to any indebtedness of Debtor to Lender
     regardless of what indebtedness or liability of Debtor to
     Lender remains unpaid and regardless of to which indebtedness
     such sums were intended to be applied unless debtor directs
     the application of such payment; (9) release any one or more
     of the undersigned, any other guarantor or any other party
     liable upon or for any indebtedness or other obligation
     guaranteed, and such release will not affect the liability
     under this Agreement of any of the undersigned or any other
     party not so released; (10) add or release the primary or
     secondary liability of principals, guarantors or other
     parties; and/or (11) obtain additional collateral security.

C.   The undersigned waives: (1) any and all acceptance of this
     Guaranty Agreement; (2) notice of the creation of any
     indebtedness; (3) any presentment, demand for payment, notice
     of default or non-payment, notice of acceleration, notice of
     disposition of security, notice of dishonor or protest to or
     upon any party and all other notices whatsoever whether
     required or permitted by this Guaranty Agreement, any other
     agreement, course of dealing, usage of trade, course of
     performance and, to the extent allowed, the law; (4) any
     exercise of any remedy which the Lender now has or later
     acquires against the Debtor and any other party; (5) any
     impairment of collateral, including, but not limited to, the
     failure to perfect, or maintain perfection of, a security
     interest in collateral; and (6) any event, or any act or
     omission of the Lender (except acts or omissions in bad faith)
     which materially increases the scope of the undersigned's risk
     as guarantor, including the manner of administration of the
     loan and changes in the form or manner in which any party does
     business or in their financial condition and any notice of any
     such change.

D.   This Guaranty Agreement shall be absolute, unconditional and
     continuing guaranty of payment and not of collection of the
     indebtedness and shall be binding upon the undersigned, heirs
     or successors of the undersigned, and the estate or estates of
     the undersigned: (1) regardless of the death or cessation of
     existence of any of the undersigned or of any guarantor or any
     other party liable upon any indebtedness or other obligation
     hereby guaranteed; (2) irrespective of any defenses, claim or
     discharge available to the Debtor under law or under any
     agreement with the Lender; and (3) irrespective of any failure
     or delay by the Lender to perfect or keep perfected any lien
     or security interest in any collateral.  This Guaranty
     Agreement is an independent obligation which is separately
     enforceable from the obligation of the Debtor.

E.   All rights of the Lender are cumulative and not alternative to
     other rights.  Suit may be brought against the undersigned or
     other parties liable, jointly and severally, and against any
     one or more of them, and against all or less than all, without
     impairing the rights of the Lender, its successors or assigns,
     against others of the undersigned.  The Lender may settle with
     any one of the undersigned or any other party for such sum or
     sums as it may see fit and release such of the undersigned or
     other parties from all further liability to the Lender for
     such indebtedness without impairing the right of the Lender to
     demand and collect the balance of such indebtedness from
     others of the undersigned not so released.

F.   The Lender may assign this Agreement or any of its rights and
     powers under it, with all or any part of the indebtedness
     guaranteed, and may assign to any such assignee any of the
     security for the indebtedness.  In the event of such
     assignment, the assignee shall have the same rights and
     remedies as if originally named in this Agreement in place of
     Lender, and the Lender shall thereafter be fully discharged
     from all responsibility with respect to any such indebtedness
     so assigned.

G.   Unless expressly limited by specific writing as set forth in
     this Guaranty Agreement, it is understood to be unlimited in
     amount.  If limited, it is understood the limit means a fixed
     amount or percentage of any indebtedness remaining after
     application of the actual proceeds of the disposition of any
     security to any unguaranteed portion of the indebtedness.
     NOTWITHSTANDING ANY PROVISION CONTAINED IN THIS GUARANTY TO
     THE CONTRARY, THIS GUARANTY IS LIMITED TO DEBTORS INDEBTEDNESS
     TO LENDER ARISING UNDER THAT PROMISSORY NOTE DATED OCTOBER
     ___, 1997, IN THE PRINCIPAL AMOUNT OF $__.

H.   Until the indebtedness of the Debtor have been paid in full,
     the undersigned agrees to provide to the Lender from time to
     time upon demand such financial statements, copies of tax
     returns, and other information as to the undersigned as the
     Lender may reasonably require.

I.   Any deposits or other sums credited by or due from the Lender
     to the undersigned may be set off against any and all
     liabilities of the undersigned to the Lender arising under the
     terms of this Guaranty Agreement.  The rights granted by this
     paragraph shall be in addition to the rights of the Lender
     under any statutory banker's lien or common law right of
     offset.

J.   Until the obligations of the Debtor have been paid in full,
     the undersigned specifically waives all rights of subrogation
     to the rights of the Lender, any claim to any security or its
     value to which the Lender has recourse, and all rights of
     reimbursement or contribution from other parties, whether
     principals or sureties, accommodation parties or guarantors.

K.   The undersigned may, only by written notice given to and
     received by Lender, withdraw only from liability for
     additional indebtedness of Debtor accepted by or incurred to
     Lender after the time of receipt of such notice by Lender.
     The liability and other agreements of the undersigned shall
     not be otherwise affected but shall continue until all
     indebtedness, including loan commitments, existing at the time
     of the receipt of such notice, and renewals or extensions of
     indebtedness to which the undersigned consents, is fully paid.
     After any such revocation, Lender may exercise any rights
     granted in this Agreement without releasing the undersigned
     from liability.

L.   Notwithstanding the provisions of any note or obligation to
     which this Guaranty Agreement applies, it is the intention o
     the parties, and it is here provided, that a Guarantor shall
     not be liable for interest charges in excess of the maximum
     amount permitted under the law applicable to this Guaranty
     Agreement.

M.   The undersigned specifically waives any right to setoff under
     12 O.S. Sec. 686, 150.S sec. 341, or any like statutes.

N.   The undersigned waive, as of the date of this Guaranty
     Agreement, any claim, as that term is defined in the Federal
     Bankruptcy Code, which the undersigned might have or acquire
     against the Debtor arising from the existence or performance
     of the undersigned's obligations under this Guaranty
     Agreement, and to that extent that the undersigned is not a
     creditor of the Debtor.  In addition to the waiver of the
     status of creditor, it is agreed that the indebtedness
     guaranteed under this Guaranty Agreement excludes all portions
     of the indebtedness paid by the Debtor during the period of
     time within one year prior to the filing of any bankruptcy,
     reorganization or insolvency proceedings by or against the
     Debtor.  If any payment made by the Debtor to the Lender is
     determined to be avoidable under applicable state law or the
     Federal Bankruptcy Code, to that extent, if demanded by the
     Lender, this Guaranty Agreement is deemed to be reinstated to
     include the amount within the indebtedness under this Guaranty
     Agreement.

O.   The undersigned, by signing below, acknowledge having read
     this Guaranty Agreement, having reviewed it to the extent
     desired with their legal counsel, and receiving a copy of it
     and also receiving an explanation of any questions.  The
     undersigned also have read any cosigner notice provided by
     Lender.  The undersigned understand that the undersigned may
     have to pay any indebtedness or obligation covered by this
     Guaranty Agreement in the event the Debtor fails or refuses to
     do so.  The undersigned also represent that they are aware of
     the financial condition of Debtor and acknowledge a
     responsibility to maintain a close watch on that financial
     condition as long as this Guaranty Agreement is outstanding
     and that they are not relying on the Lender to provide
     information on the Debtor's financial condition, now or in the
     future.

P.   This Guaranty and the obligations evidenced in it are to be
     construed and governed by the laws of the state indicated in
     the address of Lender shown above.

Q.   This Guaranty Agreement constitutes the entire agreement
     between the parties with respect to the obligations of the
     undersigned and the rights of the Lender under this Guaranty
     Agreement.  This Guaranty Agreement cannot be amended except
     by an agreement in writing signed by both the undersigned and
     the Lender.  No condition as to the effectiveness or
     enforcement of this Guaranty Agreement exists except as stated
     in this Guaranty Agreement.  Regardless of any other provision
     of this Guaranty Agreement to the contrary, and unless
     otherwise specifically released or modified by this Guaranty
     Agreement, all other obligations of the undersigned to Lender
     evidenced by a note, loan agreement, guaranty or any other
     written agreement remain in force and effect.
